There was a fluctuation of power around Shao Xuan, and the people in this casting room could feel it, but they didn't understand why Shao Xuan wanted to do this, and it wasn't the power of the totem.

The people in the foundry room were at a loss, they couldn't read, but they didn't take their eyes off, they wanted to know what the Great Elder wanted to do with this knife.

As Shao Xuan's thumb moved, a long strip of blood was left on the knife that was not too dark in color. But even if the color of the blood stains is not deep, it also shocked the people who saw this scene next to them.

This shouldn't be!

According to the strength of Shao Xuan's fingers just now, rubbing on the knife should not leave such blood marks!

For example, when a few people snatched the knife just now, someone's hand was scratched, and the blood dripped on the knife, if you didn't wipe off the blood on the knife body with your clothes, and wiped it directly with your fingers, you can also wipe off the bloodstains, and if you can't wipe it off, it won't leave many traces, far more than what Shao Xuan left just now.

Where Shao Xuan's fingers swiped, there would be such blood marks, as if the blood was no longer the liquid they were familiar with, but became extremely viscous, like cooked grain, and when the fingers were pressed and slid on it, they would leave such marks.

But that's blood!

It's so weird!

The bloodstains were just one of them, and the next scene, they were even more shocked.

I saw Shao Xuan, who was standing there, after wiping a blood stain from the blood droplet on the knife, he slapped his palm on it, just at the end of the blood stain.

Whew――

There was a flame coming out of Shao Xuan's palm, and almost at the same time as the flame came out of the palm, the flame burned along with the blood mark.

Burn...... It's burning!

It burned up!

Those who saw this widened their eyes.

There was no wood, no charcoal, and that knife would suddenly burst into flames!

No, that's no ordinary flame.

The people in the foundry room reacted quickly. They are too sensitive to fire, whether it is ordinary fire or fire related to fire, the totem warriors can tell it, let alone them. But it is precisely because of this that they are more and more surprised.

It's the power of the tinder. That's right, unlike the primordial fire, it is similar to the power of the fire fused in their bodies, but it has the power and deterrence of the fire itself.

But even if it is a fire-related work, it will not burn on a knife, how did the Great Elder do it?

"That's really the case!" Shao Xuan looked at the flames on the knife and said in a low voice.

The thought that flashed in his mind before was the scene when he led the fleet to explore down the Yan River, and the Gu tribe people he saw in the Gu tribe working together to fight against the fierce beasts. At that time, the net of the Gu tribe entangled the fierce beast, and the net on it was all burning. Later, Shao Xuan also tried, and at that time, Shao Xuan was immersed in a very mysterious artistic conception, as if he knew how to do it and what kind of result he would get.

At that time, the silk thread that bound Shao Xuan's neck around the beast burned in the same way. It's just that when Shao Xuan tried again afterwards, he didn't succeed again. One was that I didn't understand that power at the time. It's not familiar, and the environment is different. Because of the fire, the Gu tribe created a special kind of battlefield, which was full of invisible and intertwined forces, and it was a more suitable area for the Gu tribe to fight, and it was out of that condition. If Shao Xuan wants to succeed again, it will not be so easy.

Second, and most crucially, almost all of Shao Xuan's attempts at that time were new bronze weapons!

Shao Xuan remembered that when he tried to ignite it with blood on the new bronze weapon, he always felt that he couldn't concentrate. It seems that there are many forces of resistance, and now, after comparing the new bronze weapon with the knife in his hand, Shao Xuan knows the difference between the two.

Not only the new bronze, but also some other things were added to the sword that Gongjia Heng built for him, so compared to the knife in his hand at this time, it was not pure enough, not enough to make the current Shao Xuan ignite successfully, because there were too many interferences in it!

Maybe in the future, when Shao Xuan is really familiar with the skills and can ignore that kind of interference, he may succeed in igniting, but at least now, Shao Xuan has only succeeded in igniting for the first time on equipment other than white worm silk.

Figuring out the reason, Shao Xuan smiled, withdrew the power to ignite the flame on the support knife, and the flame that originally burned along the blood marks was suddenly extinguished, until it was still the same knife, there was no obvious change, as if the flame just now did not exist. It's just that the blood marks on the blade of the knife have faded a lot.

Shao Xuan touched the blade of the knife and chopped a few more pieces of wood, but he didn't find any substantial changes in the knife, so he was relieved.

Maybe it's because the blood ignited just now is too little, the flame burns for too short a time, or the material of the knife itself is more able to withstand this kind of burning, in short, I don't see any obvious changes in the knife for the time being, after all, when I was in the Gu tribe, those burned nets and silk threads turned to ashes.

When you try to start a fire with blood in the future, you still have to pay more attention, don't burn it, the knife has changed.

Shao Xuan left satisfied, leaving the people in the casting room standing there with a bewildered expression.

The creation of the knife proves that Crystall's heart can forge weapons no less than new bronze, which is exciting, but Shao Xuan still has a doubt that has not been resolved.

He took a leather roll to the Yanhe trading area to find Yi Si.

It was rare to see Shao Xuan, Yi Si was surprised, but after seeing what was written on the animal skin scroll that Shao Xuan opened, Yi Si temporarily put aside other things.

"You wrote these?" Yi Si looked at the circles and symbols on the animal skin scroll, which was their Yi family's way of calculating. But apart from Yi Si, there is no second Yi family here.

However, as early as when he was on the other side of the sea, Yi Si knew that Shao Xuan had a strong ability in calculation, so he calmed down after only being a little surprised.

"You want me to explain this?" Yi Si asked.

"Not bad. As for the remuneration, you can mention. "This is some of the hardships that Shao Xuan encountered in the process of calculation, and I can't solve it for the time being, which uses a lot of weird algorithms of the Yi family, so Shao Xuan will come to find Yi Si.

"Reward?" Yi Si thought for a moment, "Remember first, I haven't thought of it for the time being, and I'll mention it later." ”

"If you offer more than I can do, you won't be able to pay. ”

"Don't worry, I still know this, and my point of being a person is to know the times. "Not much to say, Yi Si still has a lot of other accounts in his hand that have not been settled, so let's get this one out of Shao Xuan first.

Once Yi Si started to measure, he would not stop, holding the pen in one hand and moving the fingers of the other hand rapidly. The animal skin scroll that Shao Xuan took out, although it was only a small piece, was much simpler than the dozens of pages of cloth accounts that Yi Si had received, but the things contained in it were not simple, and they were the essence of the Yi family's proudest thing.

It was such a small piece of animal skin, and the things listed in it made Yi Si keep counting for most of the day. By the time the math was done, the sun was already at a deflection.

"Give!" Yi Si wrote the calculated results on the animal skin scroll, threw it to Shao Xuan, and rubbed his eyes, "Remember the reward you promised!"

"Rest assured, you won't be on the pay. ”

Shao Xuan took the animal skin roll and left, this was only one of the steps in the calculation, he still needed to make the later calculations by himself. (To be continued.) )
